I have been using a some proven steps to create my own Oracle Linux 6uX ISO images with a custom kickstart script for a long time. What i basically do is mount the iso-image using hdiutil, copy the contents to a working folder, make the modifications and create an iso using makeiso (cdrutils). Details have been described here; http://www.reddipped.com/2015/12/virtualbox-soa-bpm-osb-bam-33-minutes/

I just made my first attempts to create a custom Oracle Linux 7u2 ISO images, but miserably failed till now.

First opening the image using hdiutil gives and 'hdiutil: attach failed - no mountable file systems'. Instead i used Keka to extract the contents of the iso. Modified the contents of the extracted iso-image;

  • Removing /isolinux/boot.cat,
  • Adding a new ks-bd.ks

  • Adding a menu item to the isolinux.cfg to be able to start installation using the kickstart file

    label linux_basicserver_silent\
  menu label ^Install basic server silent\
  menu default\
  kernel vmlinuz\
  append initrd=initrd.img ks=cdrom:\/ks-bd.ks\

Then created an iso again;

## Make isolinux.bin writable
chmod u+w V100082-01U/isolinux/isolinux.bin

# Build the V100082-01Uiso
cdrtools/cdrtools-*/mkisofs/OBJ/i386-darwin-clang/mkisofs -r -J -T -o V100082-01U.iso -b isolinux/isolinux.bin \
-c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R \
-m TRANS.TBL -v -V Oracle\ Linux\ 7.2 ./V100082-01U

After mounting the iso image and selecting the 'linux_basicserver_silent' installation option the installation seems to stall on the message 'Starting automated install'

enter image description here

When selecting a standard interactive installation in the installation menu the installation also freezes with the latest step 'Reached target Basic System'

enter image description here

After some minutes the same error 'dracut-initqueue timeout' is repeatedly shown .

Any hints how to fix this?

When comparing the orignal iso with the created iso using mkisofs there are no substantial differences, i think..

  • In OEL 7.x several parameters have been renamed. Instead of `ks=filename` you use `inst.ks=filename`. Add `nomodeset` as well. – alvits Oct 27 '16 at 01:50
  • Ok, will try those. But will not fix my issue, because when selecting the standard interactive installation proces in the repackaged ISO it also fails. – pcvnes Oct 27 '16 at 13:55
  • That's why I recommended adding `nomodeset`. Without `nomodeset`, OEL 7.x is trying to find the graphic mode of your console. That's why it cannot proceed beyond target Basic System. – alvits Oct 27 '16 at 18:47
  • Tried it and does not make a difference. When running the installation using the kickstart script it is not trying to find the graphic mode. Do not think this is the issue. I think some setting in the makeiso is not correct. If i unzip the original ISO and rebuild it using mkisofs i alsoget the same errors as on the last screenshot when choosing one of the default installation options. – pcvnes Oct 27 '16 at 19:52

Instead of using 7zip, use the cdrtool utility isoinfo to extract the original iso image.

mkdir V100082-01U
cd V100082-01U
isoinfo -R -X -i ../V100082-01.iso

Then modify the image and rebuild using mkisofs

## Make isolinux.bin writable
chmod u+w work/isolinux/isolinux.bin

# Build the V100082-01Uiso 
cdrtools/cdrtools-*/mkisofs/OBJ/i386-darwin-clang/mkisofs -r -J -T -o V100082-01U2.iso -b isolinux/isolinux.bin \
-c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -sysid LINUX \
-m TRANS.TBL -v -V OL-7.2\ Server.x86_64 ./work
